[Pro re nata anti-VEGF treatment results for neovascular age-related macular degeneration in routine clinical treatment: comparison of single with triple injections]. / Pro-re-nata-anti-VEGF-Behandlungsergebnisse bei neovaskulärer altersabhängiger Makuladegeneration in der klinischen Routineversorgung: Vergleich von Einzel- mit 3er-Injektionen.

BACKGROUND: Different injection regimens from continuous to pro re nata (PRN) have been proposed for treatment of neovascular age-related macular degeneration (nAMD). So far the PRN single injection on reactivation regimen has not been compared to the PRN triple injection on reactivation regimen (IVAN scheme). OBJECTIVE: Comparison of the two nAMD PRN injection regimens with single and triple injections on reactivation in a real-world setting in a retrospective case series in two German treatment centers. MATERIAL AND METHODS: Naïve nAMD patients, who started treatment according to either the single or triple injection regimen were included. Endpoints were best corrected visual acuity (LogMAR), central retinal thickness on optical coherence tomography (µm) and number of injections, all at 3, 6, 12, 18 and 24 months after treatment initiation. RESULTS: A total of 146 patients with single injection and 148 patients with triple injection regimens were included. There were no significant differences between the two treatment regimens in best corrected visual acuity (single vs. triple injection scheme: 0.50 ± 0.42 vs. 0.56 ± 0.42, p = 0.14), central retinal thickness (303 ± 76.2 vs. 306 ± 110, p = 0.79) and number of injections (13 ± 4.4 vs. 12 ± 5.4, p = 0.31). This was the case for all analyzed time points. CONCLUSION: There were no significant functional or morphological differences between the two PRN injection regimens with single and triple injections on reactivation after 24 months. For evaluation of long-term therapy results further studies are warranted.

Awareness of Age-Related Macular Degeneration in Community-Dwelling Elderly Persons in Germany.

Background: Due to current demographic trends age-related macular degeneration (AMD) is becoming more prevalent. When disease progresses to late-stage neovascular AMD, rapid initiation of treatment is required to achieve optimal outcomes. However, many affected individuals may be unaware of their disease impeding and delaying care seeking. Therefore, in an exploratory study we assessed whether elderly persons living independently in the community were aware of their AMD. Methods: Participants were recruited in eleven seniors' community centers. Participants underwent a standardized interview followed by non-mydriatic fundus photography of the macula and the optic disc in both eyes (Canon CR-2AF, Canon, New York, USA). The images were graded by an ophthalmologist and the data were analyzed descriptively. Results: A total of 281 participants (73.9 ± 8.1 years; 71.9% women) underwent bilateral fundus photography. The fundus photographs of 208 participants (74%; 73.6 ± 7.0 years; 73.1% women) could be graded. In a third (32.2%, n = 67) no pathological changes were detected. AMD was present in 24.5% of the examined subjects (n = 51). Half of the cases had early (47.1%), followed by intermediate (41.2%) and late (11.7%) AMD. Only one third (n = 16, 31.4%) were aware of their disease. Conclusions: A quarter of community dwelling elderly had AMD but only a third of these were aware of being affected with AMD. This confirms previous studies demonstrating low awareness for age-related eye diseases in the community. Considering the increase in population aging, awareness campaigns for AMD are needed.

[Reasons for delayed and discontinued therapy in age-related macular degeneration]. / Gründe für Therapieverzögerung und -abbruch bei altersabhängiger Makuladegeneration.

BACKGROUND: Critical prerequisites for successful therapy of neovascular age-related macular degeneration (nvAMD) are an early initiation and continuous monitoring; however, delays in starting therapy and non-medically indicated discontinuation of therapy are frequent, which limits therapy efficacy and, thus, visual outcomes. OBJECTIVE: To identify the reasons for delay in therapy and non-medically indicated termination of therapy. MATERIAL AND METHODS: Patients who had started a new therapy (starters) and those who independently terminated therapy (dropouts) were interviewed by telephone with a specific, standardized questionnaire. Results were summarized descriptively. RESULTS: A total of 100 starters and 55 dropouts were interviewed. The mean therapy delay was 22 (±28 SD) days. This was mainly due to the time until the decision to see an ophthalmologist was made. Main reasons for dropping out were: transportation issues (27%), poor general health (25%) and the assumption that there is no benefit from therapy (11%). Of the patients who dropped out 63% would have liked to continue therapy. CONCLUSION: There is potential for improvement in nvAMD management regarding therapy start as well as therapy maintenance. Sensitizing for initial nvAMD symptoms is important as is reduction of barriers to therapy maintenance, since most therapy dropouts would like to continue the therapy.
